^^^^This. I am in no way an expert, but I do know my employer (before I retired) really pushed these plans as it was cheaper for them.
For the employees, it depends on how much they use their plans. For healthier people, these plans are great and allows for opening a HSA which can grow to give the employee a pool of money to help offset future cost. I went this way when I worked and saved almost a 100k that I can use for any medical cost in the future. My only regret was not doing it sooner. But if you use your plan, it is harder to build that nest egg.
When you pencil it out, the high deductible plans make sense. They have maximum out of pocket cost, I think mine was ~$6k. If I did use the plan and maxed out my cost, it was still cheaper than the full menu plans.
I am now on my wife's plan which has great coverage. She works for the State and will work for a few years.
